+//    This class implements the worker model run manager for TBB based
+//    application.
+//    It is instantiated by tbbUserWorkerInitialization and used by
+//    SimpleTbbMasterRunManager.
+//    See G4WorkerRunManager for documentation of methods relative to
+//    base class. Only class specific methods are documented here.
+//
+// Equivalent in traditional MT:
+//    G4WorkerRunManager
+//
+// History:
+//    Oct 31st, 2013 A. Dotti - First Implementation
